Dell Laptop Wifi Driver

A recent check of the drivers for my laptop on the support page under its Service Tag showed several needed updating. All went through ok until the WiFi driver and Bios update. The WiFi driver install failed. I attempted to download it from the support site to try again but it just hangs and nothing downloads.

Dell Laptop Wifi Driver


A missing or outdated network adapter driver can cause your laptop not to connect to WiFi. To rule it out as the cause of your problem, you should update your network adapter driver to the latest version.

Do you know how to check what kind of wifi card you have? It is usually intel or broadcom based (judging by the drivers dell makes available for your model.). If intel based, you can download the most recent drivers directly from intel. If broadcom based, it will be harder to find updates but may be possible depending on which specific card you have.

It can be the most frustrating moment that you are disconnected to the wireless network when surfing on the internet with your Dell computer. Gemerally, it is the Dell WiFi driver that triggers the no WiFi issue on your Dell laptop or destop.

@OussD After a lot of research, the problem is usually solved by resetting the bios to default, mainly on dell laptops. The problem is caused after doing bios update or installing windows 11.Also don't forget to install the updated drivers.

Everyone, try removing the driver then shutting down the OS, not reset/reboot. I've been fighting this for 2 days straight and even after a complete OS reinstall/downgrade from 11 to 10 the problem is still there. Immediately after the reinstall the wifi adapter worked, but after a few reboots it went back to the same issues/events in the system log. Then I tried removing the driver and shutting down completely before powering back on and the wifi is now working. For how long who knows, but give this a shot if you are struggling.

Having older drivers installed could mean certain wireless-capable devices, such as laptops, may not be able to recognize the WiFi network being broadcast by a WiFi 6-capable gateway or router. This could prevent certain devices from connecting to your in-home WiFi network until the driver has been updated.

IIRC Broadcom WiFi devices began disappearing from most laptops about 3 months ago (despite an apparent price advantage over Intel and Atheros). The Big OEM's Ink supply contracts infrequently (they don't like to disrupt major parts and carry multiple parts in their supply channel) but it takes about 3 months for a contract to hit the supply chain, particularly for manufacturers like HP that don't do JIT manufacturing. Dell part changes hit quicker, usually less than 30 days. And Broadcom was a big at Dell, holding court over almost every Wifi Sold by Dell for a number of years.My laptop had issues over Labor day so I was looking at options at various manufacturers, one thing that surprised me quite heavily was the apparently complete lack of Broadcom Wifi at Dell now along with HP and others. Everything was Intel Wifi. This is especially surprising because in the past Dell has said there was a significant price advantage to Broadcom over Intel when questioned about Linux drivers.I deduced that Dell has finally dropped Broadcom because of Linux compatibility, but that may not be the reason. Either way something has happened in the supply contracts to make Broadcom FOSS drivers, something big because they were adamant in the past they would never FOSS drivers. Maybe I'm over optimistic, but HP has been talking about Linux drivers being a requirement for a year or more. A bit late Posted Sep 10, 2010 9:03 UTC (Fri) by bangert (subscriber, #28342) [Link]

When I bought the 610 and for several years later the default Wifi on all the Dell Laptops (that I I looked at) were Dell branded Broadcom chipsets. The typical upgrade cost as I mentioned was anywhere from $20 to $50 dollars. That's a hell of a premium on Laptop even when they still cost upwards of $1500 and it's astronomical with prices half that. But as I said when I checked the other day (on the models I looked at) the Dell branded option isn't even there anymore (and that's astounding in itself given Dell's desire to Brand everything possible). I couldn't even find laptops with Broadcom Wifi chipsets (I didn't look that far, just at a few major models and Brands). That's a hell of a change from default on every laptop at Dell. This is anecdotal evidence at best but for me it's pretty conclusive when taken into account against Broadcom's earlier statements that they would release FOSS drivers when Hell froze over (I believe the actual wording was Never because it would reveal competitive information). I can't see any other reason they would release FOSS drivers other than as mentioned in the thread that they got tired of updating their drivers and want to pass the burden to the Kernel team.

Problem: driver needed to activate wifi card is bcmwl5.....when i install the driver and restart wlan0 works fine but the eth0 is not recognized in terminal with the 'ifconfig' or 'iwlist scanning' commands. I can get eth0 to work by uninstalling the driver and restarting.

I have a rather nonstandard installation - Windows Server 2008 R2 on a Dell Latitude E6520 laptop. I want the Windows DNS server to run when the laptop starts up, but it looks like the network drivers don't present the NIC as being ready until a network cable is plugged in, because if I try to start the DNS service before the cable is plugged in, I get the error:

So is there a way to get the Dell laptop network driver to start even when the network cable is not plugged in, or get the Windows DNS service to start with no NIC available? The silly thing is that once the Windows DNS service is started, it stays running even when you unplug the network cable - it just needs it plugged in to start up in the first place! I know I can start the laptop with the ethernet cable plugged in, or manually start DNS after it's been plugged in, but it would be nice just to have it start on boot no matter what.

My Dad and I just had a totally bonehead / useless experience with Dell warranty support, for a wifi adapter in a 1 year old desktop. The tech displayed gross incompetence, telling us to install a Bluetooth driver instead of a wifi driver.

i have a Dell 7559 laptop with a 960M GTX Nvidia card, core i7-6700 and 6GB of RAM. EVERY-single-time the Nvidia driver gets installed i get BSOD DPC_WATCHDOG_VIOLATION. this is whether it installs through Microsoft windows update, whether i install it manually, whether i install it before the other drivers, or after, or in any order. using windows 11 or 10, or using the Dell official recovery software. whether i reformat the drive or fully clean it. as soon as the Nvidia driver starts installing, my computer gives the BSOD blue-screen and then will no longer boot up whatsoever. ive tried startup repair, uninstalling feature or service pack updates, restoring, etc. the only way to get it to boot even a little is to either completely reset the pc, reformat the hard drive, or boot into safe mode .. ive tried getting this computer going with different hardware even to see if there is a difference, nothing makes a difference (ive tried different RAM, m.2, sata III harddrive, etc) ... I've also tried different versions of Nvidia driver. ive tried the oldest, the newest , and some in between. no difference. and also i ve tried only installing the driver with no additional components (through custom install, and only check the Nvidia driver)..
